Ancient Beginnings (Prehistoric to 4th Century BC)

Prehistoric Times:

• Early humans likely used plants, minerals, and animal products to treat illnesses, based on trial and error, and passed on knowledge orally. This period represents the very first use of medicinal substances.
• Archaeological evidence shows that ancient civilizations in Africa, Asia, and the Americas utilized various plants for medicinal purposes long before recorded history.

Ancient Egypt (c. 3000 BCE – 500 BCE):

• The Ebers Papyrus (circa 1550 BCE) is one of the earliest known medical texts from Egypt. It contains references to herbal remedies, including opium, myrrh, and cannabis.
• Hippocrates, a Greek physician (c. 460-370 BCE), often referred to as the “Father of Medicine,” argued that diseases were caused by natural factors, not the wrath of gods, and promoted the use of herbs and diet for treatment.

• Mesopotamia and Egypt (3000 BCE): The earliest recorded use of medicines comes from the Sumerians of Mesopotamia. They used plant-based remedies and herbal compounds for a variety of ailments. Similarly, ancient Egyptians used poppy seeds (source of morphine) and other natural substances for pain relief and other medical conditions.
• Chinese Medicine (around 2700 BCE): Ancient Chinese texts like the Shennong Ben Cao Jing (Divine Farmer’s Materia Medica) compiled by Shennong detailed hundreds of medicinal herbs and their applications. This early pharmacology laid the foundation for Traditional Chinese Medicine (TCM) and herbalism that still influence modern practices.
• Greek and Roman Influence (circa 500 BCE – 500 CE):
  • The Greek physician Hippocrates (circa 460 – 370 BCE) is often regarded as the father of medicine. While not a pharmacologist in the modern sense, he emphasized the use of natural substances (e.g., herbs and minerals) to treat illness.
  • Dioscorides, a Greek physician who served in the Roman army (circa 40 – 90 CE), wrote “De Materia Medica,” a comprehensive work on medicinal plants. This book was used for over 1,500 years in Europe and the Middle East as a foundational text for herbal pharmacology.
  • Galen, a Roman physician (circa 129 – 216 CE), advanced pharmacological knowledge through his experiments with drugs and understanding of their effects on the body. He also emphasized the concept of balance in body fluids, which was a precursor to later pharmacological theory.
